Sad news...
I have received a mail from the designer of the circuit board of the HP-41CL (Monte Dalrymple), where he tells me that he has run out of units in his last production batch. He will only restart production in case there is enough interest on it. So, if you were planning to buy one, you're out of luck for the time being.
However, you can try to make a free reservation, just by sending an email to jose@thecalcuatorstore.com, so that I can forward to monte together with other requests ( I have already three of them)
